Represents the exhaust outlet which is the connection part with the

Next, the filling process will be explained based on FIGS. 2a-e and FIGS. 4 to 6 showing cross-sections of the main parts of the valve block 6.

(I) Raise the container 1 and press the rubber rubber 26K of the lower part 21 of the main body against the opening of the container 1.

After that, the counter pressure valve 15 is
), the CO2 gas from the filling tank 2 flows into the container 1 through the CO2 gas supply pipe 17, the counter pressure person 1, the TaCO2 gas communication hole 17b, and the spout 8, and the container 1 is filled with VCCO2 gas, and the internal pressure of the filling tank 2 increases. Container T
When the internal pressure of the air cylinder device 19 becomes the same as the internal pressure of the air cylinder device 19
b closes the counterpressure valve 15 via the plunger 19.

■ Pushinger 19d by cylinder device 19arc
The beer valve 11 and the exhaust valve 13 are opened through the opening to perform filling (Fig. 2b).

When the beer valve 11 opens, the beer/L/B led from the filling tank 2 to the valve block 6 via the beer supply pipe 161 and the beer volume 16a flows into the container T from the spout 8, and flows into the container T. air [However, at this point CO
] flows through the exhaust passage 12 toward the exhaust chamber 3 of the beer tank 1 via the vent tube 9, the float valve 14, and the exhaust valve 113.

Note that here, since the positive force of the exhaust chamber 3 is set lower than the pressure of the filling tank 2, the beer B in the filling tank 2 is pushed out by the back EE of the filling tank 2.

Further, since the exhaust chamber 3 is provided with a pressure regulating valve as described above, the air flowing into the exhaust chamber 3 is discharged to the atmosphere when the pressure reaches a predetermined pressure V-.

■ When the liquid opening of beer A7B flowing in from the spout 8 reaches the specified position at the top of the container 1 [the tip of the vent tube 9], the beer B flows into the exhaust passage 12 and the float valve 14
The check ball 14a is pushed up to the 7-plane surface 14b to completely close the exhaust passage 12 (see FIG. 2C and FIG. 5).

Therefore, the inflow of beer B from the filling tank 2 is stopped,
Filling is completed.

The beer valve 11 and exhaust valve 13 are then closed by the cylinder device 19a.

Here, the internal pressure in the empty space after filling is equal to the back pressure of the filler 2, so in order to lower the container T, the operation plunger 20a of the snift valve 20 [see Fig. 4] ) to open the snift valve 20 and release the pressure in the empty space to the atmosphere.

(2) After the empty space is depressurized, the container T is lowered to separate the valve block 6 and the container 1 [Fig. 2 d].

While the container 7 is being lowered, the pusher 22a of the sweeper valve 22 is operated to communicate the base passage 8a with the atmosphere, causing the remaining beer in the spout 8 to fall into the container T.

(g) When the container 7 is removed, the counter pressure valve 15 is opened to clean the remaining beer in the spout 8, and the operation plunger 23a of the blow-off valve 23 is
is operated to cause the remaining beer in the vent tube 9 and the float valve 14 to be blown out from the vent tube 9 using the internal pressure of the exhaust chamber 3.

After the remaining beer has been cleaned, the next container T to be filled is again pressed against the lower part 210 of the main body 210 and the rubber 26, and the same process is repeated.

When cleaning the filling device, the switching knob 24a of the locking device 24 (see FIG. 5) is set to 600° so that the cleaning liquid flows from the filling tank 2 to the exhaust chamber 3 via the valve block 6.
By rotating the ball receiver 24b, the ball receiver 24b is
b is interposed between the check ball 14a and the check ball 14a to prevent the check ball 14a from floating.

Note that the check ball 14a is provided with an automatic locking device, and it is possible to maintain the state in which the check ball 14a is prohibited from floating.

FIG. 6 shows the relationship between the exhaust valve 13 and the blow-off valve 23.
3b and 23o are exhaust valves 1 in the exhaust passage 12, respectively.
The bypass passages 12a between the upper and lower sides of the exhaust valve 3 and both ends of the blow-off valve 23 are exhaust ports communicating with the exhaust outlet 18a.

Further, in FIGS. 2 a-e, some valves in the passage closed state, such as the snift valve 20, sweeper valve 22, and blow-off valve 23 in FIG. 2 avc, are partially omitted.

As explained above, according to the present invention, since the exhaust air from the container 1 is configured to flow into the exhaust chamber 3 separate from the filling tank 2, the beer B in the filling tank 2 is contaminated with air. In addition, a counter pressure valve 15 is provided in the gas supply passage from the filling tank 2 to the base passage of the spout pipe, and an exhaust valve 13 is provided in the exhaust passage from the container.
Therefore, after supplying gas from the filling tank 2 to the container T via the counter pressure valve 15 to make the internal pressure of the filling tank 2 and the container T the same pressure, the counter pressure valve 15 By closing the filling tank 2 and opening the exhaust valve 13, the container 7Vr can be filled with the filling liquid from the back of the filling tank 2, and the filling speed can be controlled by the magnitude of the pressure difference between the internal pressure of the filling tank 2 and the internal pressure of the exhaust chamber 3. is possible.

Furthermore, the exhaust chamber 30 excess pressure, which is adjusted by the pressure regulating valve so that the internal pressure is lower than the filling tank pressure and higher than the atmospheric pressure, can be supplied to the float valve 24 and the vent tube 9 by operating the blow-off valve 23. , the residue inside the float valve 14 and the vent tube 9 can be cleaned, and filling can be performed reliably despite the simple configuration.
